Embodiment Construction

[0032] The intelligent protective dry-type air-core reactor of the present invention uses different sensors to collect real-time voltage and current change signals and temperature change trends of the dry-type air-core reactor, and at the same time obtains the working power of the sensor by means of electromagnetic induction; the collected real-time signal Through the signal collection device 21, it is transmitted to the protection control device 31 for monitoring and processing. When the set parameter critical value is reached, the protection control device 31 sends corresponding control signals to the vacuum circuit breaker 41 and the fan 42 to complete the dry-type air-core reactor. heat dissipation and relay protection.

[0033] Such as figure 1 As shown, the intelligent protective dry-type air-core reactor of the present invention includes a dry-type air-core reactor 01, a temperature sensor 11, a voltage transformer 12, a current transformer 13, a signal acquisition devi...

Abstract

The invention relates to an intelligent-protection-type dry-type air-core reactor which comprises a dry-type air-core reactor, a temperature sensor, a voltage transformer, a current transformer, a signal collecting device, an electromagnetic induction power supply and a protection control device, wherein the temperature sensor collects the partial temperature signal enveloped by the coil of the air-core reactor; the voltage transformer collects the voltage variation signal enveloped by the coil of a dry-type air-core reactor; the current transformer collects the current variation signal enveloped by the dry-type air-core reactor; the signal collecting device receives various real-time signals transmitted by a sensor, and converts each signal into the preset formatted data, and transmits the preset formatted data to the protection control device; and the protection control device receives the real-time data sent by the signal collecting device, and outputs corresponding control signals to a vacuum circuit breaker and a fan when the critical parameter value is achieved. The intelligent-protection-type dry-type air-core reactor provided by the invention can complete the monitoring of the own operation state in operation. The invention also comprises the control method of the dry-type air-core reactor.

Description

technical field [0001] The invention relates to a reactor and a control method, in particular to a dry-type air-core reactor and a control method. Background technique [0002] At present, dry-type air-core reactors have the advantages of low noise, good inductance linearity, and no magnetic saturation, and play an important role in reactive power compensation and maintaining system voltage stability. However, the relay protection of dry-type air-core reactors has always been difficult solved problem. Through the analysis and investigation of a large number of accidents, faults such as super high operating temperature of the internal winding of the dry-type air-core reactor and inter-turn short circuit were discovered after dense smoke or open flames were found, and then the faulty reactor was removed by manual operation. At this time, the entire reactor has been severely ablated. [0003] In order to solve the problem that the dry-type air-core reactor cannot achieve rela...
